Portable Document Format (PDF) files provide a way to distribute documents consistently across various platforms. You will need a PDF reader to view these documents. Your computer or browser may already have a PDF reader installed. You can download a free copy of PDF Reader from the Adobe Reader Website (http://get.adobe.com/reader/).

Excel (XLS) and Word (DOC) files may be viewed in Microsoft Excel and Microsoft Word. If you do not have access to these applications, you can try using OpenOffice (http://www.openoffice.org/), a free productivity suite provided by Apache.
